How to Remove Squirrels in Attic

What's the best way to get rid of squirrels in my attic? I've heard mothballs will deter them. --Frank Marasco, Austin, Tex.

Yes, the smell of mothballs can deter squirrels from nesting in your attic. (They should be scattered sparingly and kept away from children and pets.) But they won't stop the little critters -- which can be destructive -- from coming in. For that, you'll need to seal any cracks or spaces that might allow entry.

Another idea: Place several humane traps (available at home-improvement and hardware stores or, possibly, on loan from your county agricultural department) around the attic to capture the squirrels, then release them outside, away from your house or in a park.
